I'm 17, i'm a virgin, the farthest ive gone with a girl is kissing and i know she was std free. Well i have a lot of these little pimple bubble looking things.

I looked up images on genital warts and mine are not as bad as the pics ive seen, there a lot smaller ,not red, and not so noticeable. But they've been there for a while and i dont know what it is. It all started when i started to masturbate a lot(couple times a day) i think. Could that be the case?

I dont know what to do and its embarressing going to a doctor.
